Abstract

The device ( 1 ) for the processing and cooking of foodstuffs includes a base ( 2 ), a container ( 3 ) with, on the outer side of its bottom ( 4 ), a fixed protecting shell ( 5 ) by means of which the container ( 3 ) stands in a positioning housing ( 6 ) provided on said base ( 2 ), a lid ( 7 ) to close said container ( 3 ), electrical heating means supported by said container ( 3 ), a shaft ( 12 ) carrying tools ( 13 ) rotatably supported inside said container ( 3 ), electric means for powering said shaft ( 12 ), and safety means at least capable of mechanically clamping the container ( 3 ) into its positioning housing ( 6 ) and of activating the electric feed of said powering means when said lid ( 7 ) moves from an open position to a closed position of said container ( 3 ) positioned in said positioning housing ( 6 ), the safety means comprising kinematic system for reversibly transforming the movement of the lid ( 7 ) between its open position and its closed position into a reversible translation stroke of a first clamping element ( 26 ) between a withdrawn position within said protecting shell ( 5 ) and an extended position outside said shell ( 5 ) wherein said first clamping element ( 26 ) engages a first clamp housing ( 27 ) provided in said positioning housing ( 6 ) and triggers a first micro-switch ( 28 ) generating a signal to activate said electric feed of said powering means.

The invention claimed is: 
     
       1. Device ( 1 ) for the processing and cooking of foodstuffs, including a base ( 2 ), a container ( 3 ) with, on the outer side of its bottom ( 4 ), a fixed protecting shell ( 5 ) by means of which the container ( 3 ) stands in a positioning housing ( 6 ) provided on said base ( 2 ), a lid ( 7 ) to close said container ( 3 ), electrical heating means supported by said container ( 3 ), a shaft ( 12 ) carrying tools ( 13 ) rotatably supported inside said container ( 3 ), electric means for powering said shaft ( 12 ), and safety means at least capable of mechanically clamping the container ( 3 ) into its positioning housing ( 6 ) and of activating the electric feed of said powering means when said lid ( 7 ) moves from an open position to a closed position of said container ( 3 ) positioned in said positioning housing ( 6 ), characterized in that said safety means comprise kinematic system for reversibly transformation of the movement of the lid ( 7 ) between its open position and its closed position into a reversible translation stroke of a first clamping element ( 26 ) between a withdrawn position within said protecting shell ( 5 ) and an extended position outside said shell ( 5 ) wherein said first clamping element ( 26 ) engages a first clamp housing ( 27 ) provided in said positioning housing ( 6 ) and triggers a first micro-switch ( 28 ) generating a signal to activate said electric feed of said powering means. 
     
     
       2. Device ( 1 ) according to  claim 1 , characterized in that said transformation kinematic system comprises a longitudinal transmission rod ( 29 ) which is adjacent to the outer lateral side of said container ( 3 ) and presents at a first its end a formation ( 30 ) for receiving the movement of a cam ( 31 ) of the lid ( 7 ) and at a second its end drive means for driving in translation at least a first arm ( 32 ) located inside said shell ( 5 ) and, in turn, operationally engaged with a first moving carriage ( 33 ) located within the shell ( 5 ) and presenting said first clamping element ( 26 ). 
     
     
       3. Device ( 1 ) according to  claim 2 , characterized in that said cam ( 31 ) is designed to transform the reversible rotation of the lid ( 7 ) between said open and closed position into a translation of the transmission rod ( 29 ). 
     
     
       4. Device ( 1 ) according to  claim 3 , characterized in that said transmission rod ( 29 ) has a translation stroke in a plane orthogonal to the resting plane of said device ( 1 ), said first arm ( 32 ) has a translation stroke in a plane parallel to the resting plane of said device ( 1 ), and said first carriage ( 33 ) has a translation stroke parallel to the resting plane of said device ( 1 ) and radial with respect to the principal axis ( 14 ) of the container ( 3 ). 
     
     
       5. Device ( 1 ) according to  claim 2 , characterized in that said first clamping element ( 26 ) comprises a first clamping pin which is positioned radially to the principal axis ( 14 ) of the container ( 3 ) and is projecting from the end of the first carriage ( 33 ) radially turned towards the outside of said shell ( 5 ). 
     
     
       6. Device ( 1 ) according to  claim 2 , characterized in that the drive means comprise at least a drive pin ( 43 ) solidly connected to the transmission rod ( 29 ) and with a longitudinal axis which tilts in relation to the direction of movement of the transmission rod ( 29 ) and the direction of movement of the first arm ( 32 ) so that said first drive pin ( 43 ) is able to apply to the first arm ( 32 ) a drive force in both directions of translation of the first arm ( 32 ) according to whether the lid is opening or closing ( 7 ). 
     
     
       7. Device ( 1 ) according to  claim 6 , characterized in that the first drive pin ( 43 ) is slidable within an aperture ( 44 ) of said first arm ( 32 ). 
     
     
       8. Device ( 1 ) according to  claim 2 , characterized in that inside said shell ( 5 ) there are guide ribs ( 45 ) for the translation of said first arm ( 32 ). 
     
     
       9. Device ( 1 ) according to  claim 7 , characterized in that said first arm ( 32 ), at the opposite end to the one where is provided said aperture ( 44 ), has a closed slot ( 46 ) in which a first grabber pin ( 60 ) slides, solidly attached to the first carriage ( 33 ). 
     
     
       10. Device ( 1 ) according to  claim 6 , characterized in that said drive means comprise a second drive pin ( 47 ) which is solidly attached to said transmission rod ( 29 ) and has a longitudinal axis which tilts in relation to the direction of movement of the transmission rod ( 29 ) and the direction of movement of a second arm ( 48 ) which is located inside the shell ( 5 ) and is, in turn, operationally connected to a second carriage ( 49 ) to which is solidly attached a second clamping element ( 50 ) movable in reversible translation between a withdrawn position inside the protecting shell ( 5 ) and an extended position outside the protecting shell ( 5 ) wherein engages a second clamping element ( 51 ) provided within said housing ( 6 ) and triggers a second micro-switch ( 52 ) generating a signal to activate the electric feed of said heating means.
